Maybe?
- The answers are not answering the question
- We need a "policy" post to point to, even for awful policies.
Bad as this new policy is, we need a place where it is officially announced. If only to know where to point users when they ask us why we left the network. If we all go and post our own answers, the official one will be lost. Especially since the official one will be heavily downvoted, so all of the others will appear before it. So in this case, I can understand why it would be better to open separate discussion posts to discuss this aberration of a policy instead of posting answers on the main one.
In addition, the announcement was posted as an answer to a question. So the normal rules should apply: only post an answer if you are answering the question in the OP. In this case, none of us isare going to answer the question. If we did post an actual answer to the question, perhaps our own interpretation or understanding of what the policy means, that could be different, but so far, all the answers posted have been answering the answer and not the question.
We are all, correctly, furious with SE for breaking their own rules and their own sites. Let's not do the same thing. Answers that are not answering the question shouldn't be posted as answers. I would rather have the local mods and/or community delete them, but I don't see why we should change the rules for this particular post and allow non-answer answers. No matter how much I happen to agree with what these answers are saying.
